Drill Bit AWTools SDS-plus 8 x 310 mm QUADRO XTREME BLACK LINE

AWTools SDS-plus 8 x 310 mm QUADRO XTREME BLACK LINE is a rotary hammer drill bit designed for use with SDS-plus chuck systems. With an 8 mm diameter and a 310 mm overall length, this drill bit provides a standard drilling reach suitable for through-holes and anchor installation in concrete, masonry and natural stone. The QUADRO XTREME BLACK LINE geometry and carbide tip are engineered to handle impact drilling with hammer drills, delivering controlled penetration and vibration behaviour for common construction and renovation tasks.

Advantages

The drill bit combines an SDS-plus shank for fast, secure mounting with a carbide cutting head shaped for efficient drilling in hard mineral materials. Its 310 mm length gives adequate reach for fixing anchors and passing cables through walls while the 8 mm diameter is a common size for many dowels and anchor systems. The QUADRO XTREME BLACK LINE finish reduces surface wear and aids debris evacuation during rotation with impact action.

Suitable for

• Drilling holes for anchors and dowels in concrete and masonry
• Installing electrical conduits or passing cables through walls
• General construction, installation and renovation tasks requiring impact drilling

Key specifications

• Shank type: SDS-plus compatible
• Diameter: 8 mm
• Overall length: 310 mm
• Tip material: tungsten carbide cutting tip
• Intended materials: concrete, masonry, natural stone
• Application: rotary hammer impact drilling

How to use

Install the QUADRO XTREME BLACK LINE bit into the SDS-plus chuck of a compatible hammer drill until it locks. Select the hammer drilling mode and start at low speed to position the bit, then apply steady pressure and increase speed as needed. Withdraw the bit occasionally to clear dust and chips for efficient cutting and to reduce heat build-up. For through-holes or anchor installation, measure and mark the drilling depth before starting and use depth stops if required.

Usage recommendations

Wear appropriate personal protective equipment, including safety glasses, hearing protection and dust mask. Use the drill bit with an SDS-plus rotary hammer matched to the bit diameter and intended material. For reinforced concrete or very hard aggregates, advance slowly and retract regularly to clear debris; replace the bit when cutting performance noticeably declines.
